video chat sollution

We're a web development company looking to purchase an already existing video chat sollution and modify it to suit our specific needs. All the changes will be handled by us so will will need to see some code before we actualy decide to buy anything.

The solution should include:

video chat client (java) - for the visitors (has to be able to handle voice, sound and text)

video chat server (can be desktop, should be able to simultaneosly host 5 clients) - for the hosters

- events (admin can notify clients &amp; hosts by email about upcomming events and hosts are able to afiliate to that event. ie: &quot;Police wemen party&quot;)

Please do not bid unless you actualy have an already made solution similar to this one and you are able to present at least a working demo. Project will be awarded to the sollution that is the closest to our spects and it's the easiest to modify.
